Patented Jan. 16, 1940 JAR Gustave Glocker, Washington, D. C., assigner to Super-Seal Vacuum Glass Container Corporation, Washington, D. C., a corporation of Delaware .Application June 21, 1938, Serial No. 214,982

provision of a jar of this character, whichis extremely simple in its construction, thoroughly reliable and effective in its operation, economically constructed, strong, durable, and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses Claims.

The invention relates to a jar and more especially to preserve jars having lid or cover seal.

The primary object of the invention is the provision of a jar of this character, wherein the lid or cover-has tted therein a rubber ring, the same being so arranged as to become seated interiorly of the jar vbody so as to effect a fourpoint seal with the lid or cover and said body at the joint between the same and at the same time affording a cushion for the lid or cover so as to avoid liability of breakage when the jars are stacked one upon the other or each is subjected to an external load.

Another object of the invention is the provision of a jarof this character, wherein the lid or cover will be clamped centered on the mouth end of the jar and pressure within the body of the jar willhave escapement exteriorly thereof vparticularly when the jar with its contents is placed within a cooker and thus a self-sealing of the lid or cap will be assured when the jar and its contents cool without any liability of damage to the sealing ring or rubber.

A further object of the invention is the provision of a jar of this character, wherein the sealing ring or rubber can be readily punctured from withoutthe jar sowas to break or destroy the vacuum within the jar when sealed and thus permitting the easy and quick removal of the lid or cover from the jar after sealing thereof.

A still further object of' the invention is the provision of a jar of this character, wherein the lid orv cover isof novel construction so that it can be economically made and in association with a rubber or sealing ring will enable a positive and self-sealing of the jar and a four-point seal circumferentially of the jar at the joint between pointed out in the claims hereunto appended.

Similar reference characters indicate correspending parts throughout the several views in the drawing'. l

Referring to the drawing in detail, A desig# nates generally a portion of the 'bodyof a jar,

'preferably of the glass type and having as usual the open mouth which -is formed with an out. struck annular rim I0 having an internal countersunk annular shoulder II providing a seat within thev mouth or open end of said jar. This mouth or open end of the jar is adapted to be closed by a removable lid or cover I2 which is of a diameter slightly smaller than the external diameter of fthe rim I0 of the body of said jar and formed in the bottom face of said lid or cover I2 is'an annular groove or channel I3 which is adapted to register with the countersunk shoulder II in the rim I0 while inwardly of this channel or groove I3 and depending from the bottom face of the lid 4or cover is anA annular backing wall I4 for a resilient sealing ring or rubber I5 which is fitted within the groove or channel I3 and is adapted for Contact with the shoulder II A still further object of the invention is the provision of a jar'of this character, wherein the lid or cover can be conveniently and easily removed without necessitating the turning of the lid or cover on the body of the jar and the said lid or cover'lifted from its seat for the opening A still further object of the inventionis the provision of a jar of this character, wherein the lid or cover can be conveniently and easily placed upon the body of the jar and by external pressure thereon will become sealed in that any pres- -that the rubber or resilient ring can be positively seatedyand effecting a uid-tight seal between the lid or cover and the body of the jar.

A still further object of the invention is the the preferred embodiment ofthe invention and in the mouth or open end of the body A of the jar for effecting a seal between the lid or cover and said jar.

'I'he ring or rubber I5 is relatively deep and has a width corresponding to the width of the chanp nel or groove I3 and by the presence of the rim I0 on the body of the jar and the wall I4 on the lid or cover a four-point contact of this ring or rubber I5 will be had therebetween and at the same time an overlap is assured with respect to the joint between the lid or cover and the body A of the jar so that a perfect fluid-tight seal is had therebetween.

The external surface of the wall I4 next to the outer edge thereof and outside of the groove or channel I3 is beveled at I6 so as to permit a spreading or expanding of the ring or rubber I5 when external pressure is brought to bear upon the lid or cover on the contacting of the ring or rubber I5 with the shoulder II when fitting the lid or cover to the jar and in this manner augmenting the sealing action by the ring. or rubber I5 when the lid or cover is in its final applied position.

Provided in the vertical inner wall I1 of the rim I0 and slightly upwardly removed from the relieve any resistance to the sealing ofthe lid or cover upon the jar.

l Opening through the outer periphery of the lid or cover I2 is a horizontal key way I9, which is outside of the wall I4 and in the bottom face of said lid or cover for intersecting the channel or groove I3 to give access to the ring or rubber I5 so that by the use of a key 20 with a punch tip or spur 2| when inserted in the key way I9 will enable the puncturing of the rubber or ring I5 and thus break or destroy the vacuum interiorly of the jar when the vlid or cover is sealed thereon. Thereby the said lid or cover I2 can be readily andeasily removed from the jar A for the opening thereof. 'I'his way I9 has the vertical passage 22 opening downwardly in thelid or cover I2 for communication with the interior of the jar to allow the iiow of compressed air or the breaking of the vacuum interiorly of the jar when the ring or rubber I5 has .been punctured in a manner as before set forth.

The key 2D is manually manipulated and on insertion within the way I9 and thereafter by 'external pressure upon the key the punch tip or spur 2| will readily puncture the rubber or ring, the latter being backed' by the wall I4 excepting at the passage 22 and thus the tlp 2| will freely pierce such ring or rubber.

Straddling the lid or cover I2 and engaged beneath the rim I0 of the jar A is a spring clip or clamp which involves a downwardly bowed springy intermediate portion 23 and downturned hook-like terminal legs 24. This clamp or clip when bridging 'fthe lid or cover permits a rise of the latter from the jar when within a cooker so as to permit the automatic' escape of pressure within the jar through the notches I8 and 4thus relieving any resistance of the lid or cover becoming sealed upon the jan during the cooling of the contents thereof and a four-point seal of the ring or rubber I5 will take place between the lid or cover and the said jar by vacuum sealing action.

While there has been mentioned the use of a key for puncturing purposes of the ring or rubber, it'is to be clearly understood that any implement susceptible of puncturing can be substituted for this key.

By reason of the formation of the wall Il and its relationship to the body mouth rim III with respect to the seat II when the cover or lid has been finally'applied to the jar the contents of the jar are prevented from contact with the rubber or ring I5 and in this manner the' possibly be any rocking action to this lid or cover which would have a tendency to break the seal or cause such lid or cover to becomel loosened upon the jar. In other words, this lid or cover when in final vacuum sealing position will be held true upon the jar without any liability whatever of a breaking of its seal excepting by extraction of such lid or cover from sealing position when intended to do so.
